, seat for the shank of a button Which'seated therein maintains the loopinexpansible; and to provide a button loop the lateral expansion ofwhich is accompanied by relative axial distort-ion of side structures.With these and other objects in view the invention consists in the novelconstructions, to be hereinafter described or claimed, for carrying outthe above stated objects and such other objects as hereinafter may bemade to appear.

For a clear understanding of the character of the invention, referenceis made to one illustrative device embodying the novel features hereindisclosed and illustrated by the accompanying drawing in Which theFigure l is an elevation of a contracted button loop; the Figure 2 is asimilar elevation, but of an expanded button loop; and the Figure 3 is aside elevation of the same button loop, the Figure 4 being an elevationof a modified form of button loop.

The device as illustrated comprises the suspension loop 1, thebutton-receiving loop 2, the normally restricted throat portion 3, andthe button-retaining loop 4. The device is chiefly made of resilientWire of Which a middle portion is bent to form the suspension loop 1,the other Wire portions depending therefrom to provide the spring sidearms 5 and 6 cooperating to provide the axially associated loops 2 and 4having the interme diate and normally restricted throat portion 3, theWire terminals 7 and 8 over-reaching one beyond the other and eachhaving at its extremity a bent tip 9 or 10 slightly extending in a rightangled direction out of the plane of the button loop. The link 11comprises preferably a sheet metal member having an edge provided withthe depression 12 Within: which the shank S *of 'a button may be seated.Spaced boreslil and 14. provided :1 by the'sheet metal link member 11accommodatethebent-tips 10 and 9, respectively,.upon

the -assembly thereonof the link 11,? and the tips i) and lOare so"upset at their head-pore tionsasto provide a permanent assembly of:

thebuttonloop parts as best illustrated by the Figure 3. ,7

When the shank Sof a button'is ineither' one or the other of theassociated loops 2901": l, as'-illustrated by the full and dotted positstionssthe-reof in the Figure *1, the normal effect of the resilient sidearms 5 and 6 is to main-1 tain-zerect'the link 11 'so'that thedepression 12 is in readiness to'receive the shank .S of "a button,"butas the shanks is urged through? the-restricted throat portion 3 therebyex paneled, as illustrated: by the Figure 2, the link' ll islaterallytipped alon the planet of thezbutton loop, and the side arms 5andf6 are relatively moved from their normal posi-f tions in axial;directions tending to give the: vbutton loop structure a distortedappearance aswexaggeratingly illustrated by'the Figure 2. The definitetendency of the resilient button loop structureto return to its normalconditioncombines the forceof the lateral and ania'ltensions of the arms5 and 6 to provide aasturdy action'not' usuallyl attainedby an ordinaryexpanding and contracting button loopu The shank S 'seated'within thedep'ression 12 of the erect "link 11, as illustrated by the-dottedpositionthereof in the Figure 1, thereby maintains; an inexpansiblebutton loop forthe reason that the link 11', thus en-' gagedby the shankS, cannot be, tipped to permit the expansion of the button loop.

. The-Figured is anelevation of amodified structure of the preferredform of button loop above described, the modified structure, as inthe'preferred'form, having the'suspen- SlOITlOiOPZl, the axiallyassociated loops Q'and 4 intermediately providedvvith the restrictedthroatrportionB, the side arms'5 and 6 however having terminalsYA and8A, respectively; upon'one and t ie same side of the stnuctur'e,sthelink 11A beingthere'inserted and-assembled to the loop structure bymeans of the righttangledbent tipsQA and flOA of the terminals 7 and 8,as in the preferred form, being pivotally engaged and upset 111 thebores 13A and 14A provided by the link 'llA. By the insertion of th link11A the button loop of the modified form, as in the preferred form, ismade expansible, the shank S of a button, urged through the restrictedthroat portion 3, laterally forcing the arms 5 and 6 against theirspring tension to assume 7 expanded positions, the relative movement ofthe arms 5' and 6 being permitted by reason ate restricted portion,the-arms having terminals and a one-piece sheet-metal linkpivotallyconnected to said terminals, said link being movable only in said planeand provided with a seat for the shank of a button and permittingtheexpansion of the restrictedportion onlv upon the unseating of theshank.

of the pivotally. linked insertion of thelink 11A. As in the preferredform, the link 11A of the modifiedform must of necessity axially IdiStort'the button loop structure as it pivotally vyields upon theforced expansion of the restricted throat portion.

I claim:

1. A button loop comprising a suspension loop having spring armsdepending therefrom and providing in axial alignment asso loop havingspring arms depending therefrom'and providing in axial alignmentassoelated loops havlng an intermediate restricted portion, the armshaving terminals normally over-reaching one beyond the other and a "linkpivotally connected to said terminals,

said link being provided With a seat for the shank of a button, the linktipping yieldingly to permit the lateral expansion of the restrictedportion only upon a slight axial distortion of the button loopstructure;

8. A button loop comprising a suspension loop having arms dependingtherefrom and providing axially associated loops in a common plane andhaving an intermediate restricted portion, the arms having terminals anda link of one piece of material pivotally connected to said terminals,said link being movable only in the plane of the loops to permit theexpansion of the restricted portion;

4. A button loop comprising a suspension loop having spring armsdepending therefrom and providingaxially associated loops in a commonplane and having an intermedi- 5 ate restrictedportion, the arms havingterminals, and a sheet-metal connecting member so mounted upon theterminals as to have a tlpping movement only in said plane to permit thelateral expansion of the restricted 3 portion only upon a slight axialdistortion of the button loop structure;
